把构件动态转换为Web Service的架构研究

WEB服务使得网络上跨平台操作以及由不同语言开发的应用程序相互之间进行操作成为可能，并具有高度的互操作性。WEB服务为基于构件开发提供了一个相对容易的方法来适应公开的网络标准。对于C＋＋和JAVA这两种构件，提出了一个能够把不同语言开发的构件动态地转换为WEB服务的架构：当客户希望调用WEB服务器上的构件时，构件将在服务器端被动态地转换为WEB服务，然后WSDL文件的URI将被传送回客户，那么用户就可以像访问WEB服务一样，通过使用SOAP消息去访问网络上的构件而不用再去考虑构件原本的开发语言和开发平台。

Research on Dynamical Conversion of Components into Web Services

Web service makes it possible to allow the open interaction of applications across platform and programming languages over the Internet. It is of high level of interoperability. Web service provides an easy way to extend component based development by adopting open internet standards. A framework to C ＋ ＋ and JAVA components for automatically converting components created in different languages to web service is presented in this paper. When the component is selected, the component will be converted dynamically into Web serve and the URI of the WSDL file will be sent back to the client. Then users can access the component residing in the server by using SOAP messages just as they access a web service without considering the lan- guage and platform restrictions.
